【摘要】：目的了解成都市9~15岁儿童青少年肉类、奶类、锌的摄入状况及青春期发育现状,并分析食物营养素摄入与青春期发育的关系。方法采用分层整群抽样法选取成都市1 328例9~15岁儿童青少年作为研究对象,采用食物频率法和24h膳食回顾法分别收集调查对象肉类、奶类以及锌的摄入状况,利用现场观测和问卷调查方法分别收集青春期发育状况及相关的基础信息。根据Tanner青春期发育标准将男女生分别进行分组,比较不同组间肉类、奶类、锌的摄入状况。结果被调查男生初遗中位年龄为13.00岁,已初遗组总肉类、红肉平均每日摄入量均高于未初遗组(P0.05),奶类平均每日摄入量低于未初遗组(P0.05);男生总肉类平均每日摄入量为青春期发育晚期组最高,发育早期组次之,未发育组最低(P0.05)。女生初潮中位年龄为12.11岁,已初潮组总肉类平均每日摄入量高于未初潮组(P0.05),奶类平均每日摄入量低于未初潮组(P0.05);女生奶类平均每日摄入量青春期为未发育组最高、发育早期组次之、发育晚期组最低(P0.05)。结论成都市儿童青少年肉类、奶类的摄入状况可能与青春期发育相关,性别差异有待进一步研究。
[Abstract]:Objective to investigate the intake of meat, milk, zinc and puberty in children and adolescents aged 15 years in Chengdu. The relationship between dietary nutrient intake and puberty development was analyzed. Methods A total of 1 328 children and adolescents aged 15 years old in Chengdu were selected by stratified cluster sampling. The intake of meat, milk and zinc were collected by food frequency method and 24 hours dietary review method, respectively. The status of puberty development and related basic information were collected by field observation and questionnaire survey. Male and female students were divided into groups according to Tanner standard of puberty development to compare different groups of meat and milk. Results the median age of the boys was 13.00 years old. The average daily intake of red meat was higher than that of the non-residual group (P 0.05), and the average daily intake of milk was lower than that of the control group (P 0.05), while the average daily intake of male meat was the highest in the late stage of puberty, followed by the group of early development. The mean age of menarche for girls was 12.11 years old. The average daily intake of total meat in the group of menarche was higher than that in the group without menarche, the average daily intake of milk was lower than that of the group without menarche (P 0.05), the average daily intake of milk in girls was the highest in the undeveloped group, followed by the group in the early stage of development. Conclusion the intake of meat and milk in children and adolescents in Chengdu may be related to adolescent development, and the sex difference needs further study.
